Visualizing the Charge Density Wave Transition in 2H-NbSe2 in Real Space
S. P. Chockalingam, C. J. Arguello, E. P. Rosenthal +9
We report the direct observation in real space of the charge density wave (CDW) phase transition in pristine 2H-NbSe2 using atomic-resolution scanning tunneling microscopy (STM). W…
Visualizing Individual Nitrogen Dopants in Monolayer Graphene
Liuyan Zhao, Rui He, Kwang Taeg Rim +15
In monolayer graphene, substitutional doping during growth can be used to alter its electronic properties. We used scanning tunneling microscopy (STM), Raman spectroscopy, x-ray sp…
Multi-vortex versus interstitial vortices scenario in superconducting antidot arrays
A. D. Thakur, S. Ooi, S. P. Chockalingam +3
In superconducting thin films, engineered lattice of antidots (holes) act as an array of columnar pinning sites for the vortices and thus lead to vortex matching phenomena at comme…
Temperature dependence of resistivity and Hall-coefficient in a strongly disordered metal: NbN
Madhavi Chand, Archana Mishra, Y. M. Xiong +8
We report the temperature dependence of resistivity (rho) and Hall coefficient (R_H) in the normal state of homogeneously disordered epitaxial NbN thin films with kFl~3.27-10.12. T…
Vortex matching effect in engineered thin films of NbN
Ajay D. Thakur, Shuuichi Ooi, Subbaiah P. Chockalingam +3
We report robust vortex matching effects in antidot arrays fabricated on thin films of NbN. The near absence of hysteresis between field sweep directions indicates a negligible res…
Tunneling studies in a homogeneously disordered s-wave superconductor: NbN
S. P. Chockalingam, Madhavi Chand, Anand Kamlapure +4
We report the evolution of superconducting properties as a function of disorder in homogeneously disordered epitaxial NbN thin films grown on (100) MgO substrates, studied through…
